Note:

Type 2296, 8191, 8198, 8199, 8316, and 8434 computers have Enhanced Security Mode. If Enhanced Security mode is enabled and there is no password given, the computer will act as if Enhanced Security is disabled.

If Enhanced Security is Enabled and an administrator password is given, the administrator password must be entered to use the computer. If the administrator password is lost or forgotten, the system board in the computer must be replaced in order to regain access to the IBM Setup Utility program.

Administrator password control

The Administrator password is set in the IBM Setup Utility program. Refer to

Chapter 5, “IBM Setup Utility program,” on page 21.

Operating system password

An operating system password is very similar to a power-on password and denies access to the computer by an unauthorized user when the password is activated. The computer is unusable until the password is entered and recognized by the computer.

Vital product data

Each computer has a unique Vital Product Data (VPD) code stored in the nonvolatile memory on the system board. After you replace the system board, the VPD must be updated. To update the VPD, see “Flash update procedures” on page 111.

Erasing a lost or forgotten password (clearing CMOS)

This section applies to lost or forgotten passwords. For more information about lost or forgotten passwords, see Access IBM on your desktop.

To erase a forgotten password:

1.Turn off the computer and all attached devices.

2.Remove the cover. See “Removing the cover” on page 32.

3.Locate the Clear CMOS/Recovery jumper on the system board. See “Identifying parts on the system board (all machine types)” on page 40.

4.If necessary, see “Replacing adapters” on page 41 to remove any adapters that impede access to the Clear CMOS/Recovery jumper.

5.Move the jumper from the standard position (pins 1 and 2) to the maintenance or configure position (pins 2 and 3).

6.Replace the cover and connect the power cord. See “Replacing the cover and connecting the cables” on page 64.

7.Restart the computer, leave it on for approximately 10 seconds. Turn off the computer by holding the power switch for approximately 5 seconds. The computer will turn off.

8.Repeat steps 2 through 4 on page 110..

9.Move the jumper back to the standard (pins 1 and 2).

10.Replace the cover and connect the power cord. See “Replacing the cover and connecting the cables” on page 64.
